i agree with this that i have find on searching for and for my personal experience too on working on intel XDK and other tools html5 to apk buildings.
"Dependency on 3rd parties for all exports
Unless you are creating a game strictly for browser/HTML5 usage, exporting to desktop or mobile is risky, as Scirra have no control over your final export quality. Since desktop uses NodeWebkit and mobile is Crosswalk, Phonegap or CocoonJS there is no guarantee that your final export performance and quality will be up to scratch for pro level 2d games. These 3rd party "browser wrappers" are very prone to breaking and introducing lag and bugs that can't be controlled from Scirra's side."
by the way im just curious, im not very interesetead in html5 export. the most important for me is the exe work fine. this chrome wrap work fine? 100% scirra's guaranteed?
